SWITCH’AIR®

non-stick Four-Legged domes Thanks to its SWITCH’AIR® process, NICOMATIC has eliminated all risk of dome sticking thusensuring efficient automatic placement and packaging in tubes for quick and easy positioning.Nicomatic offers one of the widest product ranges on the market.

The SWITCH’AIR® notchhelps to create a cushion of airbetween the domes so thatthey no longer stick together.

DESCRIPTION ADVANTAGESThe SWITCH’AIR® non-stick domes offer :n Excellent tactile effect even after rigorous tests (click ratio > 50%)n Very long life expectancy : up to 5 million cyclesn Stable forces and homogeneity of forces per batch numbern Control of dimensional and mechanical characteristics n No burrs, thus eliminating the scratching effectn Successful and reliable automatic placement with NICOMATIC machinesn Domes in tubes save routine manual pre-separation of the domes by the operatorn The standard model is pre-nickel plated to avoid all risk of contaminationn 100% traceability per batch number
